COMBINATION HOPPER. AND FUEL-FEEDING AND DISTRIBUTING CONSTRUCTION FOR FURNACES.

Application filed January 26, 1923. Serial No. 615,112.

To all whom it may concern:

Be it known that I, CLARENCE W. Voor, a citizen of the United States, and a resident of Louisville, county of Jefferson, and State of Kentucky, have invented a certain new and useful Combination Hbpper and Fuel-Feeding and Distributing Construction for Furnaces; and I do hereby declare that the following is a full, clear, and exact description thereof, refcrence being had to the accompanying drawings, in which like numerals refer to like parts.

This invention relates to a combination hopper and fuel feeding and distributing construction for furnaces, boilers and the like. I

The chief object of this invention is to construct a construction of the charac -ter indicated in such a manner that hand stoking is possible and the resultant fuel distribution is of uniform character.

The chief feature of the invention, in ad dition to the accomplishment of the foregoing objects, is a furnace opening provided with a pluralit of fan-tail shaped spreader plates witi which are associated a plurality of hopper supported aligned and seated rams, each being in alignment with one of the spreader plates.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims.

In the drawings, Fig. 1 is a longitudinal sectional view of a furnace showing a portion of a grate and the hopper associated therewith. Fig. 2 is a rear perspective view of the hopper including the spreader plates. Fig. 3 is a front perspective view of the hopper including the spreader plates and actuating mechanisms.

In the drawings 10 indicates a furnace construction having a grate 11 and a single mouth 12. Positioned in the mouth 12 is a plurality of corrugated coking plates 13 each having a supporting bracket portion 14 adapted to support said plate in inclined position so as to discharge the fuel re-' 13. Slidably supported in each depression 19 is a ram 21 having a lower and pushing face 22 and a rack-toothed under face 23.

The hingedly supported back plate 17 permits the rams to be slidably supported between the bottom 18 and the same. Each depressed portion 19 is apertured as at 24, and positioned upon opposite sides of the slot or opening 24 is a rearwardly extending bracket 25 which forms a sup-port or car for a pivot 26 upon which is pivotally mounted a sector gear or gear segment 27. A handle 28 is associated therewith for tilting the gear segment upon its pivot. The teeth of the gear segment extend through aperture 24 and mesh with the rack teeth 23 upon the back of the ram 21. In this manner, movement of the handle from the position shown in Fig. 1, counterclockwise, to a lower position, serves to withdraw the ram from the mouth 12 of the furnace into the space between the back plate 17 and the bottom plate 19. Thereafter a clockwise or upward return movement of the handle 28 serves to move the ram from its upper and retracted position into its lower or forward position. In this movement, the ram forces the coal or other solid fuel on to the spreader plates 20, and from thence fuel passes on to the coking plate 13 to be subsequently discharged upon the grate, where it is completely burned. As shown clearly in Figs. 1 and 2, the ram above the forward face 22 and along the edge thereof is provided with a plurality of teeth 29 which assist in the movement of the coal when it is being fed into the furnace and permit the ready retraction of the ram in the retractile movement thereof.

Suitable lugs 30 and 31 positioned respectively upon the bottom 18 and the ends 15 provide retaining means for holding the rams in place upon the bottom plate 19. The spreader plate is suitabli connected to the bottom by means of the olts 32. The intermediate in 33 and end flanges 34 are adapted to rigidly secure the hopper in position adjacent the furnace 10 and in 1uxtaposition to the furnace mouth 12.

The invention claimed is:

1. In a furnace having an opening, the combination of a hopper extending upward- 'ly and outwardly therefrom, a plurality of rams arranged in spaced and parallel rela tion and slidably supported therein for discharging fuel into said opening, -and aplurality of divergingly corrugated spreadsame in a body substantially the full width of the o ening in width.

2. A claim 1 characterized by the hopper having suitable recesses therein for receivingv said rams and a hinged plate having its free edge bearable on the hopper bottom and clearing said rams. ,v

In witness whereof, I have hereunto affixed my signature.
